According to the story, after every Quantas Airlines flight the pilots complete a 'gripe sheet' report, which conveys to the ground crew engineers any mechanical problems on the aircraft during the flight. The engineer reads the form, corrects the problem, and then writes details of action taken on the lower section of the form for the pilot to review before the next flight. It is clear from the examples below that ground crew engineers have a keen sense of humor - these are supposedly real extracts from gripe forms completed by pilots with the solution responses by the engineers. Incidentally, Quantas has the best safety record of all the world's major airlines.
